Abstract
A gasket (10) comprises a first sealing member (12) and a second sealing member (14) both made of springy metal, and a clamping member (16) which holds the first and the second sealing members in an overlying relationship. The first sealing member (12) has an arm portion (12a) projecting from the clamping member (16), the arm portion being adapted to resiliently form a seal with a first body. The second sealing member (14) has an arm portion projecting from the clamping member (16), the arm portion being adapted to resiliently form a seal with a second body. A compression limiting stop (16e) is provided.
Claims28
A gasket adapted when clamped between a first body and a second body to seal the gap between the first and second bodies around a chamber or passage jointly defined by the bodies, the gasket forming a ring extending around a hole which corresponds to the chamber or passage, wherein the gasket comprises:
- a first sealing member;
- a second sealing member;
- and
- a compression limiting stop abutment;
- wherein
- the first sealing member having a first arm portion projecting from the compression limiting stop, the first arm portion of the first sealing member being adapted to resiliently engage the first body to form a seal therewith at a location spaced from the stop,
- the second sealing member having a second arm portion projecting from the compression limiting stop, the second arm portion of the second sealing member being adapted to resiliently engage the second body to form a seal therewith at a location spaced from the stop, and
- the first and second sealing members being resiliently arranged to engage the first and second bodies, respectively, to form a seal therewith at a location spaced from the compression limiting stop when the first and second bodies engage the stop characterized in that the first and second sealing members are both made of springy metal and in that a clamping member is arranged to hold the first and second sealing members in an overlying relationship.
An embodiment comprising:
- a first body;
- a second body;
- and
- a gasket clamped between the first and second bodies to seal the gap between the first and second bodies around a chamber or passage jointly defined by the first and second bodies, the gasket forming a ring extending around a hole which corresponds to the chamber or passage, wherein the gasket comprises,
- a first sealing member,
- a second sealing member, and
- a compression limiting stop wherein,
- the first sealing member has a first arm portion projecting from the compression limiting stop, the first arm portion of the first sealing member resiliently engaging the first body to form a seal therewith at a location spaced from the stop,
- the second sealing member having a second arm portion projecting from the compression limiting stop, the second arm portion of the second sealing member resiliently engaging the second body to form a seal therewith at a location spaced from the stop, and
- the first and second sealing members resiliently engaging the first and second bodies, respectively, to form a seal therewith at a location spaced from the compression limiting stop when the first and second bodies engage the stop characterized in that the first and second sealing members are both made of springy metal and in that a clamping member holds the first and second sealing members in an overlying relationship.
A method of sealing two bodies with a gasket comprising:
- clamping the gasket between a first body and a second body to seal the gap between the first and second bodies around a chamber or passage jointly defined by the bodies;
- and
- forming a ring with the gasket extending around a hole which corresponds to the chamber or passage, wherein the gasket comprises
- a first sealing member,
- a second sealing member, and
- a compression limiting stop wherein,
- the first sealing member having a first arm portion projecting from the compression limiting stop, the first arm portion of the first sealing member resiliently engaging the first body to form a seal therewith at a location spaced from the stop,
- the second sealing member having a second arm portion projecting from the compression limiting stop, the second arm portion of the second sealing member resiliently engaging the second body to form a seal therewith at a location spaced from the stop, and
- the first and second sealing members resiliently engaging the first and second bodies, respectively, to form a seal therewith at a location spaced from the compression limiting stop when the first and second bodies are brought together to engage the stop characterized in that the first and second sealing members are both made of springy metal and in that a clamping member holds the first and second sealing members in an overlying relationship.
